Description
TECHNICAL FIELD
The present invention relates a cosmetic containing a cyclic
silicone.
BACKGROUND ART
A silicone typified by dimethylpolysiloxane has features such as a
light touch, a good spread, excellent water repellency, and high
safety, and therefore in recent years, the silicone has been often
used as an oil used for the cosmetic.
For example, a cosmetic containing a volatile cyclic siloxane such
as octamethyltetrasiloxane (D4), decamethylpentasiloxane (D5), or
dodecamethylhexasiloxane (D6), a linear siloxane having a viscosity
of 0.65 to 6 mm.sup.2/second at 25.degree. C., or a volatile
siloxane having a branched siloxane chain such as
tristrimethylsiloxymethylsilane (M3T) has a light touch, a good
spread, and excellent water repellency when the cosmetic is applied
to the skin (Patent Document 1).
However, these silicones have problems in which the compatibility
with a polar oil is poor and the silicones cannot be mixed as they
remain clear, and therefore the feeling of use and stability of the
cosmetic may be deteriorated. In particular, this trend is
significantly represented when an organic ultraviolet absorber is
used. When the silicones have low affinity for an oily component
mixed for solidification of a cosmetic, such as a wax,
crystallization of the oily component is prevented, and an expected
hardness of a preparation cannot be obtained.
To solve the problems, that is, to enhance the compatibility with a
polar oil, a wax, or the like, use of a phenyl-modified silicone,
an ester, or the like as a compatibilizer is known. In this case,
the feeling of use is poor, and a light touch of silicone may not
be lost. Further, most of oil such as the phenyl-modified silicone
and the ester has nonvolatility or does not have high volatility,
and therefore an oily feeling may be strongly felt after
application of a cosmetic to the skin.
To control the volatilization rate after application of a cosmetic,
Patent Document 2 proposes a cosmetic composition containing a
mixture of at least two types of cycloalkyl methicones having
different volatilization rates as a technique using a cycloalkyl
methicone for a cosmetic. However, Patent Document 2 does not
disclose use of a cyclic silicone to improve the compatibility with
a polar oil, a wax, and the like. Since the at least two types of
cycloalkyl methicones having different volatilization rates are
necessary, formulation design is also complicated.
Patent Document 3 discloses use of a silicone that is a composition
of [--R.sub.2SiO--].sub.n (wherein R is an alkyl group having 1 to
4 carbon atoms, and n is 3 to 10, and preferably 3 to 7) in an
antiperspirant. However, a description about mixing compounds other
than dimethylcyclo methicone is not found in Patent Document and
use of a cyclic silicone to improve the compatibility with a polar
oil, a wax, and the like is not disclosed in Patent Document 3.
Further, Patent Document 3 does not disclose use of a cyclic
silicone to achieve desired volatility and feeling of use.

SUMMARY OF INVENTION
Technical Problem
In view of the above situation, it is an object of the present
invention to provide a cosmetic which has a light touch, a good
spread, and excellent water repellency, forms a uniform cosmetic
film, can achieve a good feeling of use without strongly feeling an
oily feeling, and has excellent stability over time and cosmetic
persistence even when a variety of oil such as a silicone, a
hydrocarbon oil, and an ester, an organic ultraviolet absorber, or
an oily component being solid at 2.5.degree. C. is mixed.
Solution to Problem
In order to solve the above-described problems, the present
invention provides a cosmetic containing at least one cyclic
silicone represented by the following general formula (1), and
having a boiling point of 205 to 255.degree. C. and a viscosity of
less than 5 mm.sup.2/s (25.degree. C.)
##STR00002## Wherein R.sup.1 is a monovalent hydrocarbon group
having 2 or 3 carbon atoms, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and
R.sup.6 are each independently a monovalent hydrocarbon group
having 1 to 3 carbon atoms, "a" is a positive number satisfying
0<a<4, and "b" and "c" are each independently a number of 0
to 3, provided that (a+b+c).ltoreq.4.
Such a cosmetic has a light touch, a good spread, and excellent
water repellency, forms a uniform cosmetic film, and can achieve a
good feeling of use without strongly feeling an oily feeling.
Further, the cosmetic has excellent stability over time and
cosmetic persistence even when an oil such as a silicone, a
hydrocarbon oil, and an ester, an organic ultraviolet absorber, or
an oily component being solid at 25.degree. C. is mixed.
In this case, it is preferable that the cyclic silicone be selected
from the group consisting of
1,3-dipropyl-1,3,5,5-tetramethylcyclotrisiloxane,
1,3,5-tripropyl-1,3,5-trimethylcyclotrisiloxane,
3,5,5-tetraethyl-1,3-dimethylcyclotrisiloxane,
1,3,3,5,5-pentaethyl-1-methylcyclotrisiloxane,
1,1,3,3,5,5-hexaethylcyclotrisiloxane,
1-propyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane,
1-ethyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane,
1,3-diethyl-1,3,5,5,7,7-hexamethylcyclotetrasiloxane,
1,3,5-triethyl-1,3,5,7,7-pentamethylcyclotetrasiloxane, and
1,3,5,7-tetraethyl-1,3,5,7-tetramethylcyclotetrasiloxane.
A cosmetic containing such a cyclic silicone can more assuredly
achieve a good feeling of use without strongly feeling an oily
feeling, and even when a variety of oil, an organic ultraviolet
absorber, or an oily component being solid at 25.degree. C. is
mixed, the cosmetic has excellent stability over time and cosmetic
persistence.
It is preferable that a cosmetic of the present invention further
contain an organic ultraviolet absorber.
The cyclic silicone in the present invention has excellent
compatibility with the organic ultraviolet absorber, and therefore
a cosmetic containing such an organic ultraviolet absorber has a
good feeling of use and excellent stability over time and cosmetic
persistence.
In this case, it is preferable that the organic ultraviolet
absorber be one or more types selected from ethylhexyl
methoxycinnamate, diethylamine hydroxybenzoyl hexyl benzoate, octyl
salicylate, polysilicone-15, t-butyl methoxydibenzoylmethane,
oxybenzone, methylene bis-benzotriazolyl tetramethylbutylphenol,
bis-ethyihexyloxyphenol methoxyphenyl triazine, and
octocrylene.
Such an organic ultraviolet absorber is preferable since the
organic ultraviolet absorber has especially excellent compatibility
with the cyclic silicone in the present invention.
It is preferable that the cosmetic of the present invention further
contain an oily component being solid at 25.degree. C.
The cyclic silicone in the present invention is preferable even
during use in combination with the component being solid at
25.degree. C. since a stick preparation or the like can be easily
prepared without preventing solidification of the oily component
due to high affinity of the cyclic silicone for the oily
component.
In this case, it is preferable that the oily component being solid
at 25.degree. C. be one or more types selected from a polyethylene,
ceresin, ozokerite, beeswax, microcrystalline wax, stearyl alcohol,
behenyl alcohol, and cetanol.
Such an oily component is preferable since the oily component has
especially high affinity for the cyclic silicone in the present
invention.
Advantageous Effects of Invention
The cosmetic of the present invention includes the cyclic silicone
represented by the general formula (1) as a base composition, and
therefore the cosmetic has a light touch, a good spread, and
excellent water repellency, forms a uniform cosmetic film, and
further has excellent stability over time and cosmetic persistence
even in a system where a variety of oil such as a silicone other
than the cyclic silicone in the present invention used for the
cosmetic, a hydrocarbon oil, and an ester, or the organic
ultraviolet absorber is mixed. In addition, during use in
combination with the oily component being solid at 25.degree. C., a
stick preparation or the like can be easily prepared without
preventing solidification of the oily component. The cyclic
silicone in the present invention has a boiling point of 205 to
255.degree. C. and expresses volatility or higher volatility, and
therefore an oily feeling is not strongly felt after application of
the cosmetic to the skin. The cyclic silicone in the present
invention has a viscosity of less than 5 mm.sup.2/s (25.degree.
C.), a feeling of use is good without significantly feeling a
sticky feeling. In the present invention, it is not necessary that
the volatilization rate be exactly controlled by combination of a
cyclic compound having high volatility with a cyclic compound
having mild volatility. Specifically, when the cyclic compound in
the present invention, that is, the cyclic silicone having a
boiling point of 205 to 255.degree. C. and represented by the
general formula (1) is used alone, the above-described object is
achieved.
DESCRIPTION OF EMBODIMENTS
The present inventor has intensively studied to achieve the
above-described object, and as a result, found that when a cosmetic
contains a cyclic silicone having a specific structure, a boiling
point falling within a predetermined range, and a viscosity falling
within a predetermined range, the cosmetic has a light touch, a
good spread, and excellent water repellency, forms a uniform
cosmetic film, can achieve a good feeling of use without strongly
feeling an oily feeling, and has excellent stability over time and
cosmetic persistence even when a variety of oil such as a silicone,
a hydrocarbon oil, and an ester, an organic ultraviolet absorber,
or an oily component being solid at 25.degree. C. is mixed, and
completed the present invention. Hereinafter, the present invention
will be described in detail.
Specifically, the present invention is a cosmetic containing at
least one cyclic silicone represented by the following general
formula (1), and having a boiling point of 205 to 255.degree. C.
and a viscosity of less than 5 mm.sup.2/s at 25.degree. C.,
##STR00003## (wherein R.sup.1 is a monovalent hydrocarbon group
having 2 or 3 carbon atoms, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and
R.sup.6 are each independently a monovalent hydrocarbon group
having 1 to 3 carbon atoms, "a" is a positive number satisfying
0<a<4, and "b" and "c" are each independently a number of 0
to 3, provided that (a+b+c).ltoreq.4.)
In the above-described general formula (1), R.sup.1 is a monovalent
hydrocarbon group having 2 or 3 carbon atoms, and specific examples
thereof include an ethyl group and a propyl group. R.sup.2,
R.sup.3, R.sup.4, R.sup.5, and R.sup.6 are each independently a
monovalent hydrocarbon group having 1 to 3 carbon atoms, and
specific examples thereof include a methyl group, an ethyl group,
and a propyl group.
"a" is preferably 1 or 2, "b" and "c" are preferably 1 or 2, and
(a+b+c) is preferably 3 or 4.
It is preferable that the general formula (1) satisfy that R.sup.1
is the same as R.sup.2, R.sup.3 is the same as R.sup.4, or R.sup.5
is the same as R.sup.5.
Since the cyclic silicone in the present invention has a boiling
point of 205 to 255.degree. C., the cyclic silicone has the same
volatility as those of decamethylcyclopentasiloxane boiling point:
210.degree. C.) and dodecamethylcyclohexasiloxane (boiling point:
245.degree. C.) Accordingly, an oily feeling is not strongly felt
after application of the cosmetic to the skin. When the boiling
point is lower than 205.degree. C. it is difficult that the
cosmetic is favorably applied and spread, and when it is higher
than 255.degree. C., an oily feeling is strongly felt.
Since the cyclic silicone in the present invention has a viscosity
of less than 5 mm.sup.2/s (25.degree. C.), the cyclic silicone can
be favorably applied and spread in the same manner as in a case of
using decamethylcyclopentasiloxane having a viscosity of 4
mm.sup.2/s (25.degree. C.), or the like, and a feeling of use is
good without significantly feeling a sticky feeling. When the
viscosity is 5 mm.sup.2/s (25.degree. C.) or more, the spread is
poor, a sticky feeling is produced, and a feeling of use is
low.
It is preferable that the cyclic silicone in the present invention
be especially selected from the group consisting of
1,3-dipropy-1,3,5,5-tetramethylcyclotrisiloxane,
1,3,5-tripropyl-1,3,5-trimethylcyclotrisiloxane,
1,3,5,5-tetraethyl-1,3-dimethylcyclotrisiloxane,
1,3,3,5,5-pentaethyl-1-methylcyclotrisiloxane,
1,1,3,3,5,5-hexaethylcyclotrisiloxane,
1-propyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane,
1-ethyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane,
1,3-diethyl-1,3,5,5,7,7-hexamethylcyclotetrasiloxane,
1,3,5-triethyl-1,3,5,7,7-pentamethylcyclotetrasiloxane, and
1,3,5,7-tetraethyl-1,3,5,7-tetramethylcyclotetrasiloxane.
Since the cyclic silicone in the present invention has excellent
compatibility with a general-purpose component to be mixed in a
variety of cosmetic, the cyclic silicone can be used in combination
with any component. For a preparation in which a silicone having
excellent compatibility with an organic ultraviolet absorber such
as ethylhexyl methoxycinnamate and used to express a light feeling
of use, a cosmetic having excellent stability over time and
cosmetic persistence can be obtained.
During use in combination with an oily component being solid at
25.degree. C., such as a polyethylene, ceresin, ozokerite, beeswax,
microcrystalline wax, stearyl alcohol, behenyl alcohol, and
cetanol, a stick preparation or the like can be easily prepared
without preventing solidification of the oily component.
Therefore, when the cyclic silicone in the present invention is
used, a cosmetic which has a light touch, a good spread, and
excellent water repellency, forms a uniform cosmetic film, can
achieve a good feeling of use without strongly feeling an oily
feeling, and has excellent stability over time and cosmetic
persistence even in a system where a variety of oil such as a
silicone, a hydrocarbon oil, and an ester, and the organic
ultraviolet absorber is mixed can be obtained and a stick
preparation or the like can be easily prepared.
When as the cyclic silicone in the present invention, two or more
types of cyclic silicone having different viscosities are used in
combination, the feeling of use and the volatilization rate can be
adjusted. To achieve a slow volatilization rate, the cyclic
silicone can be used alone for a cosmetic without strict
adjustment.
In the present invention, when an ultraviolet light shielding
effect is desired for a cosmetic, it is preferable that an
ultraviolet absorber be mixed.
The ultraviolet absorber is not particularly limited as long as it
is a raw material capable of being usually mixed in the cosmetic.
Specific examples thereof include homomenthyl salicylate,
octocrylene, t-butyl methoxydibenzoylmethane,
4-(2-.beta.-glucopyranosiloxylpropoxy-2-hydroxybenzophenone, octyl
salicylate, diethylamino hydroxybenzoyl hexyl benzoate,
oxybenzone-6, oxybenzone-9, oxybenzone-1, polysilicone-15,
1-(3,4-dimethoxyphenyl)-4,4-dimethyl-1,3-pentanedione, octyl
dimethoxybenzylidene dioxoimidazolidine propionate, oxybenzone-2,
terephthalylidene dicamphor sulfonic acid,
2,4,6-tris[4-(2-ethylhexyloxycarbonyl)anilino]-1,3,5-triazine,
methylbis(trimethylsiloxy)silyl isopentyl trimethoxycinnamate,
drometrizole trisiloxane, 2-ethylhexyl para-dimethylaminobenzoate,
isopropyl para-methoxycinnamate, ethylhexyl methoxycinnamate,
bis-ethylhexyloxyphenol methoxyphenyl triazine, oxybenzone-3,
oxybenzone-4, oxybenzone-5, phenylbenzimidazole sulfonic acid, and
methylene bis-benzotriazolyl tetramethylbutylphenol. Further, an
UVA absorber (e.g, diethylamino hydroxybenzoyl hexyl benzoate) and
an UVB absorber (e.g., ethylhexyl methoxycinnamate) can be used
together, or in any combination.
Among these, one or more types of organic ultraviolet absorbers
selected from ethylhexyl methoxycinnamate, diethylamino

EXAMPLES
A cyclic silicone (cycloalkylsiloxane) used in a cosmetic of the
present invention was produced as follows. The viscosity is a
viscosity measured at 25.degree. C. with an Ostwald viscometer.
(Production Example 1) Synthesis of
1,3,5,7-Tetraethyl-1,3,5,7-tetramethylcyclotetrasiloxane
241 g (1.0 mol) of 1,3,5,7-tetramethylcyclotetrasiloxane and 2.4 mg
of chloroplatinic acid were placed in a 1-L four-necked flask. An
ethylene gas was blown into the mixture, and a reaction was caused
while the temperature was held at 50 to 60.degree. C. The reaction
was monitored by gas chromatography. At a time point when the ratio
of a target reached 90% or more, the reaction was terminated, and
distillation under reduced pressure (120.degree. C., 10 mmHg) was
performed to obtain
1,3,5,7-tetraethyl-1,3,5,7-tetramethylcyclotetrasiloxane as the
target. The boiling point was 245.degree. C. and the viscosity was
4.5 mm.sup.2/s.
(Production Example 2) Synthesis of
1-Ethyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane
1-ethyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane was obtained as
a target in the same manner as in Production Example 1 except that
1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane was used as a siloxane
raw material. The boiling point was 210.degree. C. and the
viscosity was 2.9 mm.sup.2/s.
(Production Example 3) Synthesis of
1-Propyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane
1-propyl-1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane was obtained
as a target in the same manner as in Production Example 1 except
that 1,3,3,5,5,7,7-heptamethylcyclotetrasiloxane was used as a
siloxane raw material and a propylene gas was blown as an
unsaturated hydrocarbon raw material. The boiling point was
220.degree. C. and the viscosity was 3.3 mm.sup.2/s.
Solubility Test of Ethylhexyl Methoxycinnamate
The solubility between the cycloalkylsiloxanes obtained in
Production Examples 1, 2, and 3 and an organic ultraviolet absorber
was evaluated by a method described below. The evaluation results
are shown in Table 1.
Evaluation Method
Ethylhexyl methoxycinnamate (sometimes referred to as OMC) and each
silicone (sometimes referred to as Sx) were weighed at a mass ratio
shown in Table 1, and shaken and mixed at room temperature for 24
hours, and the dissolution state after 12 days at room temperature
was observed. The results are shown in Table 1.
For the dissolution state, dissolution is represented by good, and
separation is represented by poor.
TABLE-US-00001 TABLE 1 Ratio of Dissolution Silicone OMC:Sx state

As shown in Table 1, it was obvious that the cycloalkylsiloxanes
obtained in Production Examples 1, 2 and 3 in the present invention
dissolved ethylhexyl methoxycinnamate more than
octamethyltrisiloxane (KF-96L-1cs available from Shin-Etsu Chemical
Co., Ltd.), decamethyltetrasiloxane (KF-96L-1.5cs available from
Shin-Etsu Chemical Co., Ltd.), undecamethylpentasiloxane
(KF-96L-2cs available from Shin-Etsu Chemical Co., Ltd.),
tristrimethylsiloxymethylsilane (TMF-1.5 available from Shin-Etsu
Chemical Co., Ltd.), decamethylpentasiloxane (KF-995 available from
Shin-Etsu Chemical Co., Ltd.), and dodecamethylhexasiloxane
(D6).
Crystallization Test of Solid Oily Component at 25.degree. C.
Influence of the cycloalkylsiloxanes obtained in Production
Examples 1, 2, and 3 on crystallization of an oily component being
solid at 25.degree. C. was evaluated by a method described below.
The evaluation results are shown in Table 2.
Evaluation Method
Each oily component being solid at 25.degree. C. and each silicone
were weighed at a mass ratio of 9:1, and heated and dissolved at
105.degree. C. for 20 minutes. After then, the resultant was
allowed to stand at 25.degree. C. for 2 days, and the hardness of
the solid material was measured with a rheometer.
Rheometer measurement condition: An automatic consistency
measurement tester RPM-101 (manufactured by RIGOSHA) was used, a
1/4 cone was set, and a penetration hardness after 5 seconds was
measured. During penetration, the presence or absence of exudation
of oil (: silicone) from a surface of the solid material was
observed. The hardness is expressed by a numeric value. A higher
value means that the solid material is hard. The absence of
exudation is represented by good, and the presence of exudation is
represented by poor.

As shown in Table 2, for the cycloalkylsiloxane in the present
invention, oil did not exude during measurement even using any
solid oily component, and it was obvious that solidification of the
oily component was not prevented. In particular, when ceresin or
behenyl alcohol was used, relatively high hardness was shown, and
it was obvious that solidification was good.
Hereinafter, the present invention will be specifically described
with reference to formulation examples of a cosmetic in Examples
and Comparative Examples, and the present invention is not limited
to these Examples. Unless otherwise specified, a mixing amount is
represented in terms of % (% by mass).
